Genesis 24:20

And she hasted and emptied her pitcher into the trough,.... The place out of which cattle drank water, being put there for that purpose, which was of wood or of stones made hollow; into this Rebekah poured out what was left in her pitcher after the servant had drank:

and ran again to the well to draw [water]; and which must be repeated several times to have enough for all the camels, for it follows:

and drew for all his camels; and there were ten of them; and these, being thirsty after so long a journey, required a great deal of water to satisfy them; therefore Rebekah must take a vast deal of pains and labour to draw water for them all until they had enough.
